The Creepster Crawler. Look at him go.

Let me explain the next few pictures. This is a creepster crawler. The PT has Joshua working in it to get him to crawl on all fours. He doesn't like to put pressure on his hands and to push up on them, so he continues to do the army crawl. This toy, allows him to be up on hands and knees and forces him to put some pressure on his hands to make them stronger. He didn't like it a first, but then he figured out he could move faster and still pick up toys to play with.
